Mechanical-magnetic locking device

A mechanical-magnetic locking device, comprising:

• a first connecting component, a second connecting component and a magnet-armature structure;
• wherein the first connecting component is provided with a locking element with a gap, the second connecting component is provided with a locking member matched with the locking element with the gap in shape;
• a magnet is provided on the first connecting component, an armature is provided on the second connecting component, the magnet of the first connecting component is coupled to the locking element with the gap, and the armature of the second connecting component is coupled to the locking member;
• or,
• a magnet is provided on the second connecting component, an armature is provided on the first connecting component, the armature of the first connecting component is coupled to the locking element with the gap, and the magnet of the second connecting component is coupled to the locking member;
• wherein
• during locking of the locking device, the magnet of the first connecting component or the magnet of the second connecting component and the armature of the second connecting component or the armature of the first connecting component approach each other, and the locking element with the gap and the locking member are moved from a non-engaged position to an engaged position by attractive magnetic force to form locking;
• and
• when opening the locking device, the magnet of the first connecting component or the magnet of the second connecting component moves relative to the armature of the second connecting component or the armature of the first connecting component, and a magnetic attracting area of the magnet of the first connecting component and the armature of the second connecting component, or the magnetic attracting area of the magnet of the second connecting component and the armature of the first connecting component is substantially unchanged or increased, allowing the locking element with the gap and the locking member to be moved from the engaged position to the non-engaged position;
• upon reaching the non-engaged position, the magnet of the first connecting component or the magnet of the second connecting component moves relatively away from the armature of the second connecting component or the armature of the first connecting component until the magnetic force between the magnet of the first connecting component and the armature of the second connecting component, or the magnetic force between the magnet of the second connecting component and the armature of the first connecting component is sufficiently weakened to separate the first connecting component from the second connecting component.
